WITNESS-SES @Qua/wn and Improv'ed Boiler, of'which the followin settler-1.1`

y t rrtlayeortcern. Be it` known'th'ati I," FRANK S. GULIoK, a citizen of the United States, and a resident'of 4Pittsbur ,in theounty of Allegheny and Statefof ennfsylv'ania,= have invented a new is a'fulLelear, exact description.

My int-'enti y, relates to boilers, and more particularly to those adapted for domestic use land in "which the source of heat consists of burnersftowhichia combustible fluid is slfifpplied. l vItsfprincipal object is to provide e e'ctive meansfforl'applying the heat'.

. Reference is'fto `be had to the accompanying drawin s, forming apart of this specification, in ichwsirnilar reference characters designate similar parts inv both the views.

Flgu'r 1 is a central vertical section through one embodiment. of my invention. Fig. 2is

necting-pipes.

a top plan view of the burners and their con- A designates va boilerhaving acylindrical portion 10, preferabl formed of sheet-metal, this having at its en s closures in the form of a cast-metal to v11 and a similar bottom 12. The-weight of t 's latter element is such that it is capable of retaining a considerable amount of heat' for transmission to the liquid contained within the boiler. From the top ofthe boiler rises an outlet-pipe 12 and at the bottom is 'a' draw-offcock 12b. Below the boiler is a supporting member 13, which also conveniently serves as a casing or inclosure for a burner B, this preferably having two concentric inner and' outer portions 14 andy 15', respectively, which are carried by bracketsl, lprojectingfrom the membery 13.

Air-openings. 17 are shown in the lower portion of the member 13,to sup ly oxygen to the burner. AIn .the top and ottom of the boiler are alined openings to receive a Hue 18, which extends from above the center of the burners. Between the burners and boiler is a coil 19, connected at one end to the bottom of the .boiler at 20. This coilis of conical v form and hasl its lower convolution situated substantiallyv above the outer burner` 15, from which 1t tapers upwardly to -a point near the axis of the smaller burner 14. The conical coil is continued through the Hue by a spiral coil 21, situatedconcentrically to the :Specification of Letters Patent. I Appliosn ned nay 10,1905.' saisir. 259.731.`

FRANKS, .sumen-or mismas. PENNSYLVANIA. ASSlGNQR DEBoL-D ANDoNE-THIRD 'T oJonNsLn-Ap l --walls'of said Hue and terminating at apoint l From the burners 14 and 15 lead pipes 24,

v and' into the Haring end 25 of each projects the nozzle .26 of a valved pipe 29, only one of The pipes 29 lead from the casing `31), wit which is connected'thepipe 31 for supplying gas or other The caswith the?- cylinder .35," which, with the casing' 30, forms an automatic controllin 'device for Y regulating the .supply of fuel. T 's control- -ling device, however, forms no'partof the ypresent invention.. From the upper' side of the cylinder 35 leads a pipe 38, which is connected with the supply-pi e 22 by a"T-coup' ling 38a. The lower 'en of the pipe 38 is connectedv withthe lower part of the'boiler by the pipe 39.l By the emplo ent' of two burners and the arrangement o the coil with respect thereto, as shown, an intense tle heat can be applied as desired.l both burners are hghted, the whole `coil and the bottom of the boiler will be subjected to the action of heat, whereas when the inner or smaller burner only is lighted, a gentle heat4 will be applied to theupper part of the coil.

or en- Villien By this means the Water can bel quickly heated and maintained heated with Vcomparatively little fuel. The thick heavy bottom ofthe boiler not only serves to assist in heating the water, but also in'keeping it hot.

Having `thus described my invention, I claim as new and desire to secure by Letters Patent- 1.-: A boiler, comprising aleylindrical body ha and sheet-metal Walls and cast-metal top ottom, 'a' Hue extending centrall through the body and above the to thereo a, tubular support for the body a urner in the suplport below the Hue of the body, a conical c'oi above the burner and terminating in a spiral coil, extending into the Hue above the top of the body, the end of the conical coil being connected with' the bottom of the b'od and a su ply-pipe extendingtransverse y through t e Hue and connected.l withthe IOO i "body above the bottom thereof,r the spiral y :the bottom thereof, the spiral coil being connected with the supply-pipe within the said lue.

3. A boiler, comprising a boiler proper, av iiue'extending through the boiler, a conical coil arranged below the bottom of the boiler and terminating at one end in a coil extend ing into the flue, the other end of the conical coil being connected with the bottom of the boiler, and a supply-pipe connected with the boiler above the bottom thereof and with 'which the upper end of the spiral coil is oonnetted..

r. l hrilrr, rrrrrrirrrI Ir lrrilrr rrrrrr having sheet-metal walls and a cast-metal, bottom,I a flue extending through the boiler, a source of heat below the bottom of the boiler, a conical coil arranged between the source of heat and the bottom of the boiler and terminating at vone end'in a spiral coil extending into the ue, 'the other end of the conical coil being connected with the bottom of the boiler, and` a supply-pipe connectedI with the boiler above the bottom thereof and with which the upper end of the spiral coil is connected.

v5. A boiler, comprising a cylindrical body having sheet-metal walls and a cast-metal 4o bottom, a Hue extending centrally through the body, a tubular supportfor the body, a source of heat in the tubular support, a conical coil between the source of eat and the bottom of the body, said coil having one end 45 connected with the bottom of the body and its other end terminating in a spiral coil extending through the flue, and a supply-pipe connected withthe body above the bottom thereof and with which the upper end of the 5o spiral .coil is connected.

. 6. A boiler, comprising a cylindrical body, a flue extending centrally through the body, a tubular support for the body, la conical coil arranged inthe su port below the lower end 5 5 of the iiue, said co' having one end connected with the bottom of the body and its other end terminating in a spiral coil extending through the flue, and` a supply-pipe extending transversely through tlrrr lrrrr rrrrd rrrrr 0o llttitd Wiiil ille iroriy airovrr tire bottom ci U the boiler and with-which the spiral coil is connected in said flue.
